Google I/O is an annual developer conference held by Google in San Francisco . It is an Expo of upcoming gadgets and software . The term I/O stands for Input/Output. First I/O meet was held on 28 may 2009.

Google I/O nineth annual developer conference has been held on may 20 . In that conference several highlighting things has been spotted . They are,...

## 1) Two billion android users

Google was happy to announce that they have crossed two billion Android user world wide . This users includes smart phone, Tab and other supporting devices.

Google assistant is nothing but the upgraded version of Google now. This Google assistant is already available for android device , which is now available for Apple device . Since Apple has siri as personal assistant now Google now competing  with that. In google voice assistant comes with keyboard feature .

Google lens is for android device . In which we can know information about particular place by taking photo. Google lens is similar to google now . This can also give rating about particular shop. Google lens also edit your old photos without any app , since they have used artificial intelligent in it. It can also connect your device with wifi just by scanning.

## Google home is another personal assistant which is given for home . By using this device we can even call with that. This feature is available for US and UK , soon they will provide for other countries.

Google photos is given with some cool upgrade we know google photos already saves photos in cloud and also identify faces and seperate them . This is provided with three cool feature
• Suggested sharing( which is to share photos with suggested people automatically)
• Shared libraries(Which is to find pics to share with specific circle)
• Photo book(It is paid service which print pics for required size)

Google is working on VR headset , They named it as standalone , which does not require any android device in it . They also making project Tango which is for blind people in Standalone .

## 7) Android "O"

Google started beta test on android O , there were many rumor that they have named this as Oreo but they not yet revealed name. This beta version is now available for Nexux and Pixel devices . Android O will feature dot notification also there were many optimization  made in this to increase performance.

## Starting  Issue in Automobile:

Most irritating thing  in motor cycle is starting problem . When rider is urgent in doing some work it happens , which create huge stress . This arises by anyone of the reason as I mentioned in below ,..

## Clutch is not engaging properly

When you are starting your bike and the transmission is in gear, you need to pull the clutch lever properly. Sometimes, the clutch does not engage correctly and creates a starting problem. In such condition, bring your transmission in neutral and try again.

Blocking intake or exhaust

Blocked airbox or muffler exit is also a condition that creates starting problem, which can occur due to any reason including pranksters in your neighbourhood. So, you should also check the intake and exhaust system of your bike if there is anything extra in them.

Engine cut off switch

It is one of the most common things we forget to check before getting annoyed with the starting problem. Most of the time we use the ignition key to turn off the motorcycle instead of the engine kill or cut off switch. So when we use it, we forget to turn off the switch sometimes and keep trying to crank the engine.

The battery that is safely secured onto
your bike is indeed the lifeline of its
entire electrical system. For two
wheeler's equipped with just an electric
start, the starter motor is wholly
dependent on the battery. Only if the
battery carries sufficient charge would it
be able to crank up the motor that demands a fairly high voltage from the battery.
On a relatively weak battery one would not be able to use the electric start. Some signs of a dead or a weak battery are when you push the horn button or switch on the headlights, none actually work well or report total failure.
No fuel

When your fuel level goes down, it is very difficult to judge its availability using the gauge and that could also be a reason why your bike isn't starting. At that time, you can use some old school techniques to check if your bike has fuel or not.
One of the easiest way is to shake your bike gently when on main stand and wait to hear that typical telltale slosh of remaining fuel, if any, from the tank. Alternatively you could also check it using the flashlight of your mobile phone.

## Loose spark plug wire

Loose spark plug wire is not a new thing for motorcycle riders; it can occur due to the jerks or could be a prank. You don't need any mechanic to fix this problem. Just unplug and re-plug the connectors and try to start the motorcycle again.

## Clogged fuel tank vent

There is a very small vent provided on the fuel tank of your motorcycle for the outlet to supply fuel continuously to the intake system. In most of the bikes in India, it is the keyhole of the fuel tank cap.
When this vent gets clogged, the tank stops the supply of fuel to the lower system. You can unclog the vent with a very thin wire or pin along with a forced blow in that hole.

## What is Anti-lock braking system?

An anti-lock braking system is also known to be Anti-skid braking system (ABS) is an braking system in automobile system which allows wheels on motor vehicle to maintain tractive contact with the road surface according to driver inputs while braking .

This ABS will prevent the wheels from locking up and avoiding uncontrolled skidding . It generally offers improved vehicle control and decrease stopping distance on dry and slipping.

## Main component of ABS

There are four main components improves this braking system . They are
• Wheel speed sensor
• Valve
• Pump
• Controller

## ABS types

1. Four-channel , Four-sensor ABS
2. Three-channel , Four-sensor ABS
3. Three-channel , Three-sensor ABS
4. Two-channel, Four-sensor ABS
5. One-channel,One-sensor ABS

## What is air gun?

An airgun is a type of gun which propels projectile by means of mechanically pressurised air or other gases without involving any chemical reaction. Since first airgun is made in 1500s. Speciality of air gun is we can use pellets spherical or any type of materials as bullet.

We have made airgun with some cool feature . Our airgun is more powerful when compared with others.

We have named our airgun as "Cheri froura" .

Why we named cheri froura?

The name Cheri froura is derived from the Greek word in which Cheri mean guard and froura means hand .

Since we may be the very first person to do air gun mounting over wrist.
Normally a wrist gun may travel for a distance of  30 feet but our Cheri froura  can travel for a distance of 42 feet approximately .

Materials used​ in Cheri froura:
Half inch pvc pipe, one inch pvc pipe,mtp (one inch to half inch ) 2 nos, half inch gate valve, bike valve tube, pvc gum, araldite and m-seal as required, sheet metal, tube.

Originally called CG guns (compressed gas guns), air guns utilizing prefilled removable gas cylinders as power source have now become known as CO2 guns due to the ubiquitous commercial use of bottled carbon dioxide gas. Most CO2 guns use a disposable cylinder called a "Powerlet", that is often purchased with 12 grams (0.42 oz) of pressurized CO2 gas, although some, usually more expensive models, use larger refillable CO2 reservoirs like those typically used with paintball markers.

## Calibers (bullet) :

The most common air gun calibers are

• .177 (4.5 mm): the most common caliber. Mandated by the ISSF for use in international target shooting competition at 10m, up to Olympic level in both rifle and pistol events. It has also been adopted by most National Governing Bodies for domestic use in similar target shooting events. It has the flattest trajectory of all the calibers for a given energy level, making accuracy simpler. At suitable energy levels it can be used effectively for hunting.
• .22 (5.5 mm & 5.6 mm): for hunting and general use. In recent years air rifles and pistols in .22" (and some other calibers) have been allowed for use in both domestic and international target shooting in events not controlled by the ISSF. Most notably in FT/HFT and Smallbore Benchrest competitions. These events often allow the use of any caliber air gun, up to a maximum which is often .22", rather than a fixed caliber.
• .20 (5 mm): initially proprietary to the Sheridan multi-pump pneumatic air rifle, later more widely used.
• .25 (6.35 mm): the largest commonly available caliber for most of the 20th century.
• .357
• .45 (11.43 mm)
• .50 (12.7 mm)
• .58 (14.5 mm)

Other less common traditional calibers include:
Larger caliber air rifles suitable for hunting large animals are offered by major manufacturers. These are usually PCP guns. The major calibers available are:
Custom air guns are available in even larger calibers such as 20 mm (0.79") or .87 (22.1 mm)

Law for air gun calculation

While in some countries air guns are not subject to any specific regulation, in most there are laws, which differ widely. Each jurisdiction has its own definition of an air gun; and regulations may vary for weapons of different bore, muzzle energy or velocity, or material of ammunition, with guns designed to fire metal pellets often more tightly controlled than airsoft weapons. There may be minimum ages for possession, and sales of both air guns and ammunition may be restricted. Some areas require permits and background checks similar to those required for firearms proper.

## Formula for calculating air gun velocity

It is very simple you can calculate the velocity of caliber from below formula

The general formula for the kinetic energy is
${\displaystyle E_{k}={\begin{matrix}{\frac {1}{2}}\end{matrix}}mv^{2}}$

Muzzle energy is the kinetic energy of a bullet as it is expelled from the muzzle of a firearm. It is often used as a rough indication of the destructive potential of a given firearm or load. The heavier the bullet and especially the faster it moves, the higher its muzzle energy and the more damage it will do.

1. Low production cost .
2. It can be use for self defence.
3. It can be operated at any temperature.
4. It can be used in various purpose  such as hill climbing ,.
